TOYOTA Tensioner Assy, V-RI; US - Part Code 166200W101

This is a genuine TOYOTA Tensioner Assembly specifically designed for V-RI engine models sold in the US. It plays a crucial role in maintaining the correct tension on your serpentine belt, which is essential for the proper functioning of various engine accessories such as the alternator, power steering pump, and air conditioning compressor. Proper belt tension is vital to prevent slippage, which can lead to reduced efficiency of these accessories and potentially cause premature wear on the belt and tensioner itself. A failing tensioner can manifest as a squealing noise from the engine bay, especially on startup or acceleration, or a visibly loose or flapping belt. By replacing your old or worn tensioner with this OEM TOYOTA part, you can restore optimal belt tension, ensure the reliable operation of your engine's accessory drive system, and prevent potential damage to other components. This assembly is built to meet TOYOTA's stringent quality and performance standards, guaranteeing a precise fit and long-lasting durability.
